Cook ground beef and chopped onion in a large pan over medium high heat until meat is no longer pink and onion is translucent. (I use my 6 quart dutch oven.) Drain off any fat.
Add minced garlic, canned tomatoes, and spices. Bring to a boil, then reduce heat to low and simmer for 20-30 minutes.
Stir in the sugar, salt, and frozen corn and heat through.
Serve over cooked rice and garnish with grated cheese.
